Original 'counts events per KST day' test used UTC times that bucket identically under both KST and naive UTC slice — would not catch a regression where kstDate was replaced with ev.ts.slice(0,10). Add an explicit near-midnight case (2026-05-01T15:30Z = 2026-05-02 00:30 KST) that fails under naive UTC and passes under correct KST conversion. 6 tests pass (was 5).
